Definition: Astrogenesis is a biological process in which cells undergo a series of changes that lead to the production and differentiation of new cells. It involves the formation of a precursor cell, called an autocrine cell, which then becomes a target cell for another cell or tissue, leading to the formation of a secondary cell. This process can be repeated until all necessary cells have been generated, forming a population of specialized cells that perform specific functions. Astrogenesis is a key step in the development of tissues and
